FELIX R. RAPIDS, OF CHICAGO, ILLINOIS PATENT orrics I HAIR CLEANING"DEVICE Application filed .Tuly29,

' maximum amount ot-v the dandruff is drawn into the openings. I p Afurther object is to provide a hair cleanmg device inlwhic h the teethare arranged to separate the hair in such a manner that the strands arethoroughly cleaned by reason of i the movement of the air passingthrough the openings in the'teeth, and in which the teeth are furtheradapted to loosen dandruff, etc. adhering to the hair throughout itsentire length and depth.

A further object is to provide a hair cleaningdevice which, whileprimarily designed for the purpose of removin dandruif, dust,

etc., is equally well adapted to remove any loose hair. e e e A furtherobject is to provide a hair cleanpose in that it may be employed as ablower for drying the hair, scalp, etc.

A further object is to provide a device of the type described in whichsharp corners and the like have been reduced to a minimum therebyproviding a device which mayv be easily cleaned. a A v Other objects andadvantages will appear in the following specification, and the novel 10features ofthe invention will be particularly pointed out in theappended claims.

My invention is illustrated in the accom panying drawings forming partof this application in which Figure 1 is a sectional View taken alongthe line 11;of Figure 2,

the device shown in Figure 2 and illustratingthe device used inconnection with a re movable cap or cover,

Figured is an end elevation of the device shownin Figure 3,

Figure 5 is an enlarged sectional detail view showing the manner inwhich the cap or cover is removably attached to the device, Figure 6 isan end elevation of a slightly modified form of my invention, and

'Figure 7 is a: further modification of my device. i h

In carrying out my invention I make use of a hollow body portion 1provided'withan integral shank portion 2. Theshank 2 is also hollow andis preferably-connected with a flexible tube 3 which is operativelyconnected with a vacuum device, not shown. The body portion 1 isprovided with a plurality. of teeth 4 havingoneof their edges providedwith openings 5 throughout. their entire length. The teeth are providedwith side walls ti and edges 7' disposed angularly with respect to theedges'provided with the openings. V

The ends of the teeth may be formed asat 8, see Figure 2, and slightlyrounded as at 9 in Figure 1. The opening 5 communicate with the opening.in the body portion 1 which is in communication with the openings in theshank 2 and the tube 3. The walls of the teeth 4 are preferably arrangedin parall'el relation. 1

In operation the teeth of the hair cleaning device are moved through thehair in sub: stantially the same manner as the ordinary comb is usedwhen'combing the hair. The points of the teeth tend to loosen anydandrufi adhering tothe scalp and the movement of'the airthrough thedevice, which must of necessitypass through the openings 1 in the teeth,draws theloosened dandrufi,

that the openings in the teeth provide a minimum amount of restrictionas when long hair and the like is passing through the openings.

The teeth, in being arranged in parallel relation and in proper spacedrelation, tend to separate the hair in thin strands which are thoroughlycleaned by reason of the movement of air through the openings 5. Anydandruff and the like which is adhering to the hair will be loosened bythe edges of the teeth. It will also be seen that when the points of theteeth are moved over the scalp the dandrufi' loosened by the teeth mentof air between the teeth, The cover may be advantageously employed whenusing the device in cleaning relativel short hair. When the cover isplaced in position and the open edges of the teeth presented to thescalp, the moving air must of necessity pass relatively close to thescalp. The cover may be made of relatively thin material which permits acertain amount of flexing of the end portions 11. Each end 11 may beprovided With a recess 12 for receiving lugs 13 associated with a pairof the teeth 4. The construction is such that the cover may be slippedinto position and the lugs 13 will firmly hold the cover in positionwhile the device is bein used.

In Figure 6 have shown a slightly modified form of my construction inwhich the edges 4' and 7 are tapered toward each other with respect tothe parallel sides 14 and 15. In Figure 7 the teeth are rounded as at16. The operation of each form is, of course, substantially identical,In either form the cross sectional area of the opening in the shank 2and the body portion 1 should preferably be e ual to or greater than thetotal cross sectiona area of the openings in the teeth, I claim:

- 1, A pneumatic hair cleaning device comprising a hollow bodyportionhaving a plurality of substantially triangular hollow teethcommunicating with the interior of the A body portion, said teeth beingflat and pro vided with openings on one side of said teeth extendingsubstantially the entire length of said side of the teeth, each of saidteeth having flatside walls, all of the side walls of all of said teethbeing substantially parallel and spaced-apart from each other, saidsides of all of said teeth provided with said openings being positionedsubstantially in a single plane, said openings being adapted to be movedadjacent the scalp.

2. A pneumatic hair cleaning device comprising a hollow body portion,and a plurality of triangular hollow teeth connected with the bodyportion and communicating with the interior of the latter, each of saidteeth being tapered in the direction of their outer ends and providedwith openings on one side extending substantially the entire length ofsaid side of the teeth, said teeth being spacedapart and parallel toeach other, said sides of all of said teeth being positionedsubstantially in a single plane, said openings being adapted to be movedadjacent the scalp.

3. A pneumatic hair cleaning device comprising a hollow body portion,and a plurality of substantially triangular hollow teeth connected withthe body portion and communicating with the interior of the same, saidteeth being flat and wider at their bases than at their opposite endsand provided with openings in one side of said triangular teethextending substantially from their bases to their outer ends, said teethbeing substantially parallel to each other, all of said sides havingsaid openings being positioned substantially in a single plane, saidopenings being so arranged in said teeth that said openings may be movedadjacent the scalp in a manner whereby said device may remove thedandruff directly from the scalp.

4. A pneumatic hair cleaning device comprising a hollow portion, and aplurality of flat hollow teeth, said teeth being provided withlongitudinal openings, said openings being positioned substantially in asingle plane, each of said teeth being positioned opposite one anotherand having side wall portions, said side wall portions beingspacedapart, opposite and substantially parallel to each other, each ofsaid openings being so positioned on said teeth that said openin may beplaced substantially opposite and a5 jacent the scalp in a mannerwhereby the dandrufi on the scalp may be drawn into said hair cleaningdevice. I

5. A pneumatic hair cleaning device comprising a hollow body portionhaving aplurality of substantially triangular hollow teeth communicatingwith the interior of the body portion, said teeth being fiat and pro.-vided with openings on one side of said teeth extending substantiallythe entire length of said side of the teeth, each of I said teeth havingflat side walls, all of the side walls of all of said teeth beingsubstantially parallel and spaced-apart from each other, said sides ofall of said teeth provided with said openings being positioned in aslightly curved formation, said openings being adapted to be movedadjacent the scalp.
